Magnetic-tape cassette apparatus comprising an auto-reverse deck with pressure-roller bracket actuation

摘要

The invention relates to a magnetic-tape-cassette apparatus comprising a deck for magnetic-tape cassettes and constructed for playing and fast winding modes in forward and reverse directions, in which the switching between the forward and reverse tape transport directions is accomplished by means of a switching lever. The switching lever controls pressure rollers mounted on a pivotal bracket which serves to pivot the pressure rollers into and out of engagement with the capstans. The pressure roller bracket includes a fork which is actuated by the movement of the switching lever. The switching lever also carries an intermediate wheel rotatably mounted thereon and a pivoting wheel pivotally mounted on the switching lever which is in engagement with the intermediate wheel. The pivoting wheel is engagement with one of the reel discs when the switching lever is in the forward direction and the other of the reel discs when the switching lever is in the reverse direction. Thus, the switching lever provides both rotation to the reel discs and movement of the pressure rollers into and out of engagement with the capstans.
